Acid-adding charging process capable of reducing charging energy consumption

Abstract

The invention provides an acid-adding charging process capable of reducing charging energy consumption. An existing charging process is improved, and the density of the acid-added electrolyte of the battery is improved; the charging energy consumption is greatly reduced by matching with a charging process mode and a current time distribution mode, the process time is shortened to 47 hours, the charging rate is 7.5 times, the energy consumption is saved by 13.8% in comparison with 8.7 times of the existing process, and the problem of higher energy consumption of the existing process is solved under the condition of ensuring the polar plate formation effect and the battery capacity.

Description

Technical field [0001] The invention relates to the field of battery manufacturing, in particular to an acid charging process for reducing charging energy consumption. Background technique [0002] At present, in the field of battery manufacturing, it is very common to use the internalization charging process to charge the battery, and the current internalization charging process for the battery generally takes a long time, and if the charging conversion process has a low rate, it will As a result, the plate formation is impermeable, the capacity is low, and does not meet the factory requirements. Therefore, the charging rate of the current mainstream power battery formation process is about 9.5 times, and some low energy consumption processes can be reduced by less than 9.0 times. However, the energy consumption of the above process is relatively high, and the production cost is relatively high. Therefore, it is particularly important to solve the problem of high energy consump...

[0002] At present, in the field of storage battery manufacturing, it is very common to use the internalization charging process to charge the battery. However, it usually takes a long time to charge the battery with the internalization charging process, and if the charging rate is low, it will be As a result, the plate formation is impermeable, the capacity is low, and it cannot meet the factory requirements. Therefore, the charging rate of the current mainstream power battery formation process is about 9.5 times, and some low-energy-consumption processes can be reduced by less than 9.0 times.

However, the energy consumption of the above-mentioned process is relatively large, and the production cost is relatively high.
